ABSTRACT:
An apparatus for cleaning the interior surfaces of an air duct includes a housing. A conduit having an intake opening at one end thereof and an exhaust opening at the opposite end thereof is coupled to the housing. Brushes are mounted to the housing for sweeping engagement with the interior surfaces of the air duct. A vacuum supply is provided to the conduit, such that dust and foreign matter which is loosened by the brushes is drawn into the conduit at the intake opening for transport to the exhaust opening. A video camera is mounted within the housing and spaced forward of the brushes for generating an image of the interior of the air duct. A display displays the image generated by the video camera during an air duct cleaning operation.
